Single-step genomic evaluation became a standard procedure in livestock breeding, and
the main reason is the ability to combine all pedigree, phenotypes, and genotypes available …

An important goal in animal breeding is to improve longitudinal traits; that is, traits recorded
multiple times during an individual's lifetime or physiological cycle. Longitudinal traits were …

The first national single-step, full-information (phenotype, pedigree, and marker genotype)
genetic evaluation was developed for final score of US Holsteins. Data included final scores …

Currently, genomic evaluations use multiple-step procedures, which are prone to biases and
errors. A single-step procedure may be applicable when genomic predictions can be …

Computing the inverse of the genomic relationship matrix using recursion was investigated.
A traditional algorithm to invert the numerator relationship matrix is based on the observation …

Implications• Leading pig breeding companies have implemented single-step evaluation for
genomic selection. Overall, this increases EBV accuracies by half.• Further improvement …

Background Bias has been reported in genetic or genomic evaluations of several species.
Common biases are systematic differences between averages of estimated and true …

Genomic evaluations can be calculated using a unified procedure that combines
phenotypic, pedigree and genomic information. Implementation of such a procedure …

Currently, the USDA uses a single-trait (ST) model with several intermediate steps to obtain
genomic evaluations for US Holsteins. In this study, genomic evaluations for 18 linear type …

Genetic evaluation for beef cattle in Australia has been performed using an animal model
with best linear unbiased prediction since 1984. The evaluation procedures have evolved …
